Description

Clariallabes longicauda is an African air-breathing catfish of the family Clariidae from the Congo basin in Central Africa. The species has a strongly elongate, eel-like body with a long tail, a flattened head and four pairs of barbels, and reaches about 28 cm. Like other clariids it has an accessory breathing organ above the gills with which it can breathe air and survive oxygen-poor water. It lives on the bottom of vegetated, slow-flowing waters. The diet is omnivorous: a stomach was found to contain remains of decayed plants and insects. Owing to its secretive habits little is known about its precise biology.
